Tim Miller, Laura Natal and the Online Distributed Proofreading Team at https://www.pgdp.net (This file was produced from images generously made available by The Internet Archive) The origin and development of the atomic theory by Maynard Shipley is a scientific publication and historical account written in the early 20th century. The book concisely traces how ideas about atoms arose, changed, and matured—from ancient philosophical speculations to modern scientific theories—showing how the concept of matter’s discreteness evolved into the foundation of chemistry and physics. Shipley begins with the Pythagoreans, Philolaus, and related ideas from India, highlighting number, geometry, and the five regular solids as early ways to picture particles. He then presents Leucippus and Democritus: atoms and void, causal necessity, subjective sense qualities, and the role of shape, size, and arrangement; along the way he contrasts them with the Eleatics’ denial of motion and Anaxagoras’ “seeds.” The narrative turns to Epicurus and Lucretius, covering equal falling speeds in the void, the swerve debate, many worlds, and a polemic against superstition and divine design. Democritus’ “soul atoms,” effluences, and theories of color and taste are explained alongside Aristotle’s critiques. The closing chapter follows post-classical atomism through Descartes and Gassendi to Dalton’s laws of definite and multiple proportions, clarifying early errors about formulas, and connects these to modern insights—electrons, nuclei, isotopes, and atomic number—showing how an ancient idea became the quantitative science of matter.
